Abstract
The present invention relates to a cooling jet nozzle (10) for an engine piston. The nozzle (10) comprises a cooling stream pathway (14), in which the internal cross-sectional dimensions of the pathway vary along the length of the pathway; and a plunger (28) located within the cooling stream pathway to impinge a cooling feedstream received within the pathway to provide a cooling jet. The plunger (28) is axially moveable within the pathway to adjust the internal cross-sectional dimensions of the cooling jet.
